Moving Rod#

In the accompanying figure, the rails, connecting end piece, and rod all have a resistance per unit length of $${{params.r }}$$ $$\rm\ \Omega$$$$/$$$$\textrm{cm}$$. The rod moves to the left at a $$v=$$ $${{params.v }} \textrm{ m/s}$$.

Part 1#

If $$B=$$ $${{params.B }} \textrm{ T}$$ everywhere in the region, what is the magnitude of the induced current in the circuit when $$a=$$ $${{params.a }} \textrm{ cm}$$?

Part 2#

Does the induced current circulate clockwise or counterclockwise?
